Tomorrow same time I am going to publish very hard 5* Yin-Yang sudoku, so if you like this kind of puzzle, do not put away your crayons after this one ;-)
But today we have rather challenging Erica puzzle, which can be figured out though - patience is the key.
Always remember: YOU ARE GREAT! Do not let anyone tell you otherwise :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.
X/V: Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5. Not all Xs and Vs are given.

That hits the spot! Very nice flow, never too easy or too difficult, always just barely enough info to allow you to progress.
